3 Description
The LMR51430 is a wide-VIN, easy-to-use SIMPLE
SWITCHER® synchronous buck converter capable of
driving up to 3-A load current. With a wide input range
of 4.5 V to 36 V, the device is suitable for a wide
range of industrial applications for power conditioning
from an unregulated source.
The LMR51430 operates at 500-kHz and 1.1-MHz
switching frequency to support use of relatively small
inductors for an optimized solution size. The device
has a PFM version to realize high efficiency at
light load and FPWM version to achieve constant
frequency, and small output voltage ripple over the full
load range. Soft-start and compensation circuits are
implemented internally, which allows the device to be
used with minimum external components.
The device has built-in protection features, such as
cycle-by-cycle current limit, hiccup mode short-circuit
protection, and thermal shutdown in case of excessive
power dissipation. The LMR51430 is available in a
6-pin SOT-23 package.
